WINDOW REGULATOR.

Application filed October 16, 1923. Serial No. 668,866.

To all whom it may concern:

Be it known that I, NORMAN MAXWELL WAGNER, a. subject of the King ofGreat Britain, and a resident of the village of Milverton, in the countyof Perth, in the Province of Ontario, Canada, have invented certain newand useful Improvements in Window Regulators, of which the following isthe specification.

My invention relates to improvements in window regulators and the objectof the invention is to devise a. simple and cheap construction of windowregulator which will be positive in action and which will hold thewindow definitely at any point desired and it consists essentially ofthe arrangement and construction of parts as hereinafter moreparticularly explained.

Fig. 1 is a sectional view through an automobile door showing the windowin the open position and my mechanism for operating the same.

Fig. 2 is an elevational view of the central portion of the door asshown in Figure l with the outside wall or plate removed.

Fig. 8 is a vertical sectional view through a fragmentary portion of thedoor showing the operating gears and handle.

In the drawings like characters of reference indicate correspondingparts in each figure.

1 indicates an automobile door, such door being hollow and provided withan inner wall 2 and an outer wall 3 and frame 4 in terposed between theouter and inner wall to space them apart. The upper member 4* of theframe 4 is provided with a slotted opening 4 for the passage of thewindow. 5 is the window. 6 is an orifice having an enlarged inner end 6in the outer wall 3 of the door. The lower member of the frame 4 isprovidedwit-h a central recess 7", such recess being located in theinner edge of the frame so that the wall 2 also forms the inner wall ofthe recess. 8 is a plate member which is cut into substantially U-shapedform, the arms 8 and 8 of which are provided at their upper ends without-turned portions 8 which extend over the upper edge of the wall 3 asindicated by dotted lines in Figure l and are secured to the upper edgeof the wall by screws or other suitable means.

The plate 8 is provided with a depending bar member 9 extending downwardto the lower member 7 of the door frame, the bar member 9 terminating ina tongue 9* fitting into the recess 7*. '10 are lazy tongs of the usualconstruction, the lower members 10 and 10 being pivoted together at 11and to the inner wall 2 of the door. 'The upper members 12 and 13 of thelazy tongs are pivoted together at 14: and to a depending lug 15 of abracket 16 in which is carried the window 5.. i

23 and 24: are bearings carried by the plate arms 8 and 8 of the plate8. 25 is a drum journalled at its ends in the bearings 23 and 24:. 26and 27 are cords which are reversely wound upon the drum 25 in proximityto each end thereof. 28 is a pulley wheel journalled upon the bar member9 in proximity to its lower end. The cord 27 extends downward from thedrum 25 and is directly connected to the pin 22 and the cord 26 passesaround the pulley wheel 28 in opposite directions and then extendsupward therefrom, their extreme end being secured to the projecting endof the pin 22. 29 is a worm wheel secured to the drum 25 at the outsideof the bearing 24.

30 is a worm carried upon a short shaft 4-3 journalled in the plate 8,the worm 30' is in mesh with the worm wheel 29 and as such worm isrotated the drum 25 is turned thereby so as to wind one cord 26 or 27upon such drum and to unwind the other cord. By this means it will beseen that an upward or downward pull is exerted upon the pin 22 toexpand or contract the lazy tongs and thereby raise or lower the. window7, the pin 22 being guided in a vertical slot 22*. In order to rotatethe worm wheel 30 I provide the following mechanism which is located inthe orifice 6 of the door hereinbefore referred to.

32 is an orifice formed in the plate 8. 33 is a covering plate securedto the outside of the wall 3 and covering the orifice 6. The plate 33 isprovided with a central opening 34*.

423 is a shaft upon which is secured the worm 3O meshing with the gear29. The outer end of the shaft 43 is threaded as in dicated at 455, anoperating handle 46 being screwed .thereonto and secured in position bya set screw 47 bearing against a reduced portion 48 of the shaft 48, asis clearly indi cated in Figure 3. a, t y

By turning the handle 4:6, the shaft a3 is rotated, turning the worm 30and the gear 29 in mesh with the gear 30 and thereby rotating the drumand alternately pulling upon the cords 26 and 27 to expand or contractthe lazy tongs and raise and lower the window. It will also be seen thatthe window will be automatically locked in any position by the worm gearand worm, it being impossible to turn the worm by the worm gear.

From this description it will be seen that I have devised a very simpleconstruction whereby a window of an automobile door may be raised orlowered to any desired position and held positively in such position sothat it cannot be moved vtherefrom either by pressure or inadvertentlyby the vibration of the car.

What I claim as "my invention is:

In a window regulator, the combination with a pocketed door, of asupporting plate, the upper portion of which is U form, the centralportion depending therefrom and embedded at its lower end in the door,bottom lugs extending inward from the upper end of the arms of the Uadapted to b e secured at the upper edge of the door pocket, a rollerjournalled between the arms of the U so as to stand inwardly from theface thereof, a set of lazy tongs the lower membersof which arepivotally connected in proximity to the bottom of the supporting, plate,a pulley ,journalled on the connecting pin, a pin extending inwardcentrally from intermediate arms of the lazy tong, a flexible corddepending from such pin around the aforesaid pulley and then upward tooneend of the drum, and a flexible cord extending upward from the pin tothe opposite end of the drum and reversely wound thereon to theaforesaid flexible cord, a worm wheel secured at one end of the drum, ashaft mounted in the upper end of the supporting plate adjacent theworm, a worm mounted upon the shaft engaging the worm wheel, and anoperating handle detachably secured to the shaft at the outside .of thedoor pocket.
